The mistery of the algae

oceano-sargassiSince a couple of days, we observed on the surface of the ocean some yellowish agglomerates which to us resemble a kind of algae. At the beginning it was just a few spot every now and then, but since this morning they became much more frequent, forming ling, wide strips moving in the opposite direction of our boat. We cannot imagine where they come from, and if the truly are algae or something else. What is astonishing is the quantity of them, at times covering large areas of the surface around us. A photo will follow. Has anybody an idea or heard of such a phenomenon?

We are 280 miles from Barbados. Since yesterday we logged 170 miles. The wind seems to be favorable, at night even too much, forcing us to reduce sails.

450 miles to go
100 nautical miles to go!

    You are fast now! I would agree with Rich and Diane: if is it a brownish yellow algae and has grapes which are the air bladders it should be sargassum. Theer is a reporting site for these type of seaweed as it can become really critical
    Good winds and safe rest of your journey!

    Could it be sargassum instead of alge? The sargassum is found only in the North Atlantic away from coastlines. You are lucky to see these floating micro bio masses – seaweed that is home to mamy species of fish and other ocean creatures. I hope it’s sargassum!
